Description
Die Erfindung bezieht sich auf ein Verfahren zum Betreiben einer Walzgerüstanlage, bestehend aus einem oder mehreren Stauchvorgerü sten, denen über Verbindungsrollgänge und eine Quertransporteinrich tung eine, quer zu den Stauchvorgerüsten versetzte Kompaktwalzgruppe nachgeordnet ist, die aus einem ersten und einem zweiten Univer salgerüst oder Duo-Gerüst und einem, zwischen diesen angeordneten Stauchzwischengerüst besteht, wobei der Walzgerüstanlage in einem vorgegebenen Zeittakt, aus einer Stranggußeinrichtung kommende Vorprofile direkt ohne Zwischenlagerung zugeführt und in der Kom paktwalzgruppe nacheinander jeweils zu profilierten Walzgußsträngen fertiggewalzt und einem seitlich der Walzlinie angeordneten Kühlbett zugeführt werden, bevor oder während das nächst folgende Vorprofil in die Kompaktwalzgruppe eintritt.The invention relates to a method for operating a Roll stand system consisting of one or more upsetting devices Most, those via connecting roller tables and a transverse transport device a compact rolling group offset across the upsetting stands subordinate, which consists of a first and a second university salt scaffold or duo scaffold and one arranged between them There is an intermediate compression stand, the roll stand system in one predetermined timing, coming from a continuous casting Pre-profiles fed directly without intermediate storage and in the com Compact roll group one after the other to form profiled rolled cast strands Completely rolled and a cooling bed arranged on the side of the rolling line be fed before or during the next following pre-profile enters the compact rolling group.
Bei diesem bekannten Verfahren weist das, hinter der Kompaktwalz gruppe angeordnete Kühlbett eine Transportbreite auf, die der Länge des fertiggewalzten Walzstranges entspricht. Diese Anordnung erlaubt es, die Walzgerüstanlage im Zeittakt mit der Stranggußeinrichtung kontinuierlich zu betreiben, wenn die von der Walzgerüstanlage erbrachte Leistung der Formung des Vorprofils in den Walzgutfertig strang die gleiche (oder eine kleinere) Zeitspanne benötigt, die auch die Stranggußeinrichtung braucht, um ein Vorprofil herzustel len.In this known method, this points behind the compact roller group arranged cooling bed on a transport width that the length of the finished rolled strand. This arrangement allows it, the rolling mill system in time with the continuous casting device to operate continuously when the of the mill stand system performed the shaping of the pre-profile in the rolled stock strand the same (or a smaller) amount of time that the continuous casting device also needs to produce a preliminary profile len.
Mit abnehmenden Querschnitt und entsprechend abnehmenden Gewicht pro Längeneinheit des zu formenden Walzgutfertigstrangs wird die zeitliche Leistung der Walzgerüstanordnung kleiner, und von einer bestimmten Profilgröße an reicht die Leistung der Walzgerüstanord nung nicht mehr aus, die Produktion der Stranggießeinrichtung im Zeittakt zu verarbeiten; es müssen dann aufwendige Zwischenlagerun gen der von der Stranggußeinrichtung produzierten Vorprofile vor genommen werden.With decreasing cross-section and correspondingly decreasing weight per unit length of the finished strand to be formed is the temporal performance of the mill stand arrangement smaller, and of one certain profile size, the performance of the mill stand arrangement is sufficient the production of the continuous caster in To process timing; elaborate interim storage is then required against the pre-profiles produced by the continuous casting device be taken.
Der Erfindung liegt die Aufgabe zugrunde, das Verfahren zum Betrei ben der beschriebenen Walzgerüstanlage so zu verbessern, daß auch die Formung kleinerer Profile im Zeittakt mit der Stranggußein richtung ermöglicht wird.The invention has for its object the method for operating ben to improve the rolling mill system described so that the formation of smaller profiles in time with the continuous casting direction is made possible.
Diese Aufgabe wird dadurch gelöst, daß beim Walzen von Profilen, deren Fertigwalzzeit größer ist als der von der Stranggußeinrichtung vorgegebene Zeittakt, ein erster Längenabschnitt des bereits aus der Kompaktwalzgruppe ausgetretenen Walzgußstranges, von diesem abgetrennt und dem Kühlbett zugeführt wird. Wie die Erfindung weiter vorsieht, soll der abtrennte erste Längenabschnitt vorteilhaft die Hälfte der Gesamtlänge des fertigen Walzgutstranges aufweisen. Die Trennung des ersten Längenabschnitts kann dabei in der Walzlinie, vor dem Kühlbett bewirkt und der abgetrennte erste Längenabschnitt aus der Walzlinie heraus auf das Kühlbett aufgebracht werden. Eine andere Möglichkeit besteht darin, daß die Trennung des ersten Längenabschnitts in der Walzlinie hinter dem Kühlbett bewirkt, dabei zunächst der zweite Längenabschnitt auf das Kühlbett aufgebracht und anschließend der erste Längenabschnitt in der Walzlinie vor das Kühlbett zurücktransportiert und auf dieses aufgebracht werden.This object is achieved in that when rolling profiles, whose finish rolling time is longer than that of the continuous casting device predefined timing, a first length section of the already the compact roll group emerged from the rolled casting, from this separated and fed to the cooling bed. How the invention continues provides, the separated first length section should advantageously the Have half the total length of the finished rolled strand. The The first length section can be separated in the rolling line, in front of the cooling bed and the separated first length section be applied to the cooling bed from the rolling line. A another possibility is that the separation of the first Longitudinal section in the rolling line behind the cooling bed, thereby first the second length section is applied to the cooling bed and then the first length in the rolling line before that Cooling bed transported back and applied to this.
Das erfindungsgemäße Verfahren kann unter Ausnutzung der Pausenzeit bis zum jeweils nächsten, in die Kompaktwalzgruppe eingebrachten Vorprofil und unter Verwertung der beiden ersten Reversierstiche, die noch relativ kurz sind, durchgeführt werden. Das Aufteilen des Walzgutstranges ist bei dessen Stillstand auf dem Rollgang möglich, so daß sich eine einfache Trenneinrichtung, wie eine Säge oder ein Schneidbrenner anstelle fliegender Sägen oder Scheren verwenden läßt.The method according to the invention can take advantage of the pause time up to the next, brought into the compact rolling group Preliminary profile and utilizing the first two reversing stitches, which are still relatively short. Splitting the Rolled material strand is possible when it stops on the roller table, so that a simple separation device, such as a saw or a Cutting torch can be used instead of flying saws or scissors.
Die Erfindung wird anhand der in der Zeichnung dargestellten Aus führungsbeispiele erläutert. In der Zeichnung zeigenThe invention is based on the illustrated in the drawing management examples explained. Show in the drawing

Fig. 2 die Draufsicht auf eine anders ausgebildete Walzwerks anlage, ebenfalls in schematischer Darstellung. Fig. 2 is a plan view of a differently designed rolling mill, also in a schematic representation.
Bei der Ausbildung nach Fig. 1 besteht die Walzgerüstanlage aus dem Zuführrollgang R1, der, aus den Universalgerüsten UG1 und UG2 und dem zwischen diesen angeordneten Zwischengerüst bestehenden Kom paktwalzgruppe, dem dieser nachgeordneten Abfuhrrollgang R2 und der seitlich dieses Abfuhrrollgangs R2 und seitlich der Walzlinie WL angeordneten Kühlbett KB sowie einer vor dem Kühlbett KB befindli chen Trenneinrichtung TR.In the embodiment according to FIG. 1, the roll stand system consists of the feed roller table R1, which, from the universal stands UG1 and UG2 and the intermediate stand arranged between them, compact roller group, the downstream discharge roller table R2 and the side of this discharge roller table R2 and the side of the rolling line WL Cooling bed KB and a separating device TR located in front of the cooling bed KB.
Die Walzgerüstanlage wird in der Weise betrieben, daß der erste, die Kompaktwalzgruppe verlassende fertige Walzgutstrang PSTI auf dem Abfuhrrollgang R2 vor das Kühlbett gefahren und zum Stillstand gebracht wird. Anschließend wird dann mit Hilfe der Trenneinrichtung TR, der vor dem Kühlbett KB liegende erste Längenabschnitt PSTI′ abgetrennt und auf das Kühlbett aufgebracht. Anschließend wird der noch auf dem Abfuhrrollgang R2 liegende zweite Längenabschnitt PSTI′′ vor das Kühlbett KB gefahren und ebenfalls auf dieses aufge bracht. Zwischenzeitlich wurde der aus dem (nicht dargestellten) folgenden Vorprofil durch zunächst kurze Reversierstiche entstehende nächste, in unterbrochenen Linien angedeutete Walzgutstrang PSTII auf den Abfuhrrollgang R2 aufgebracht und nach seiner Fertigwalzung entsprechend geteilt und die entstandenen Längenabschnitte auf das Kühlbett aufgebracht.The mill stand is operated in such a way that the first finished rolled strand PSTI leaving the compact rolling group the discharge roller table R2 in front of the cooling bed and stopped brought. Then using the separator TR, the first length section PSTI ′ lying in front of the cooling bed KB separated and applied to the cooling bed. Then the second length section still lying on the discharge roller table R2 PSTI '' driven in front of the cooling bed KB and also on this brings. In the meantime, the from the (not shown) following pre-profile created by initially short reversing stitches next rolled strip PSTII indicated in broken lines applied to the discharge roller table R2 and after its finish rolling divided accordingly and the resulting lengths on the Cooling bed applied.
Die Ausbildung der Walzgerätanlage nach Fig. 2 entspricht im Grund satz der nach Fig. 1 mit der Maßgabe, daß das Kühlbett KB in einem, etwa der Länge eines Längenabschnitt eines geteilten Walzgutstranges entsprechenden geringeren Abstand von der Kompaktwalzgruppe angeord net ist, und die Trenneinrichtung TR hier, in Walzlinie WL gesehen, hinter dem Kühlbett befindet. Der aus der Kompaktwalzgruppe aus tretende, auf dem Abfuhrrollgang R2 liegende Walzgutstrang PSTI wird hier, vor dem Kühlbett KB auf dem Abfuhrrollgang R2 liegend mit der Trenneinrichtung TR getrennt und dann, anders als bei der Ausbildung nach Fig. 1 zunächst der, in Transportrichtung gesehen, hintere Längenabschnitt PSTI′′ auf das Kühlbett KB aufgebracht. Anschließend wird der zweite Längenabschnitt PSTI′ auf dem Rollgang R2 entgegen der Walzrichtung zurückgefahren, vor das Kühlbett KB gebracht und auf dieses aufgeschoben. Mit dem folgenden Walzgutstrang PSTII wird entsprechend der bei Fig. 1 geschilderten Weise verfahren; auch hier mit der Maßgabe, daß zunächst der hintere Längenabschnitt PSTI′′ und dann der vordere Längenabschnitt PSTI nach vorherigem Rücktrans port auf das Kühlbett KB aufgebracht werden.The formation of the rolling device system of FIG. 2 corresponds in principle to that of FIG. 1 with the proviso that the cooling bed KB in one, about the length of a longitudinal section of a divided Walzgutstranges is net corresponding smaller distance from the compact rolling group angeord, and the separating device TR here, seen in the WL rolling line, behind the cooling bed. The rolling stock PSTI emerging from the compact rolling group and lying on the discharge roller table R2 is separated here in front of the cooling bed KB on the discharge roller table R2 with the separating device TR and then, unlike in the embodiment according to FIG. 1, first seen in the transport direction, rear length section PSTI '' applied to the cooling bed KB. Then the second length section PSTI 'on the roller table R2 is moved back against the rolling direction, brought in front of the cooling bed KB and pushed onto it. The following rolling stock strand PSTII is used in the manner described in FIG. 1; also here with the proviso that first the rear longitudinal section PSTI '' and then the front longitudinal section PSTI are applied to the cooling bed KB after prior return transport.
